FAQs

Why is a standby generator a smart investment for homes and businesses in Elizabethton?

Carter County routinely experiences power interruptions caused by Appalachian thunderstorms, winter ice, and equipment failures along the mountain grid. A permanently installed generator automatically restores power within seconds, keeping HVAC systems, medical devices, well pumps, security equipment, and point-of-sale systems running. Beyond convenience, it helps prevent frozen pipes, food spoilage, lost revenue, and costly downtime, providing true uninterrupted energy for your property.

How do I determine the correct generator size for my needs?

Start by listing the appliances and systems you want powered during an outage—refrigerators, HVAC, sump pump, lights, computers, etc. Add their running watts and the highest starting watt draw. Our team then performs a site survey, load calculation, and voltage-drop analysis to recommend a generator—typically 7–22 kW for most homes and 25 kW+ for small businesses. Correct sizing ensures the unit can handle peak load without over-taxing the engine or alternator, which prolongs equipment life and reduces fuel costs.

What fuel options are available and which is best for Elizabethton?

We offer generators that run on natural gas, liquid propane (LP), or diesel. For most homes tied to the City of Elizabethton gas line, natural gas is the most convenient—no refueling and lower emissions. Rural properties without gas service often choose LP because tanks can be placed above or below ground and propane stores indefinitely. Diesel is preferred for large commercial or industrial loads due to higher energy density. During the site visit we evaluate fuel availability, run-time requirements, and local codes to recommend the optimal choice.

How fast will the generator restore power after an outage?

Our automatic transfer switch (ATS) senses a utility failure within one second, signals the generator to start, and transfers the electrical load once voltage and frequency stabilize—typically within 10–15 seconds total. When utility power returns, the ATS re-transfers the load back to the grid and cools down the generator before shutting it off. This seamless process means you won’t have to manually start the unit or plug in extension cords.

What maintenance is required to keep my generator reliable?

Like any engine, a generator needs periodic service. We recommend an annual preventive maintenance plan that includes oil and filter changes, spark-plug inspection, valve clearance check, battery test, air-filter replacement, coolant and belt inspection, and a full load-bank test. Between visits, the generator’s onboard controller performs weekly self-exercises to circulate fluids and run diagnostics. Regular maintenance preserves your warranty, prevents unexpected failures, and ensures the unit is ready for the next outage.

Do you handle permits, installation, and warranty service, and what can I expect for cost and timeline?

Yes. We manage the entire turnkey process—load assessment, equipment sizing, utility and zoning permits, concrete pad or gravel base, fuel line installation, electrical wiring, ATS integration, final inspection, and customer training. Residential projects typically cost $7,000–$12,000 installed, while small commercial systems range from $15,000 and up depending on capacity and fuel type. Once equipment is in stock, installation takes 1–2 days with inspections completed within a week. We are an authorized dealer for Generac, Kohler, and Briggs & Stratton, so we can register and service your warranty locally in Elizabethton.
